[00:18:23] <BigJohnT> alex_joni: WEEEEE! I cut up a 4' x 8' sheet of 12 gauge this evening into little parts!!!
[00:21:23] <tomp2> granthes: (if you read back ) you might try this code to test your encoders http://wiki.linuxcnc.org/uploads/pyvcp-dro2.hal from this page http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?PyVCP
[00:50:49] <fenn> BigJohnT: let's see some pics
[01:31:57] <skunkwork1> Got I/O? http://www.pastebin.ca/961646
[01:47:26] <cradek> neato
[02:10:00] <Guest252> Guest252 is now known as skunkworks
[02:52:00] <tomp2> skunkworks: is that the futurlec?
[02:53:12] <skunkworks> yes
[02:54:27] <skunkworks> that and the mesa card should give us 4 axis + 120 i/o
[02:55:04] <tomp2> way cool i got same hdwr
[02:55:21] <skunkworks> you have a futurlec card?
[02:55:41] <tomp2> yep, i think i got 2 years ago, were very cheap, came from thailand
[02:56:01] <tomp2> cool box, lotsa squiggly lines
[02:56:14] <skunkworks> yes - you can still get them. There are some issues with the drive.. But I am sure they will be straitened out.
[02:56:30] <skunkworks> *hal driver
[02:58:57] <skunkworks> http://www.futurlec.com/PCI8255.shtml
[02:59:36] <tomp2> thats it & the hal driver doesnt talk to the tiger chip, thats pretty unknown
[03:00:15] <tomp2> hey, still cheap!
[03:03:06] <skunkworks> It works - there is just some issues with certain i/o configs - if I set all the pins to inputs... the computer hardlocks. :) jepler hopes to look at it this weekend if he gets a chance.
[03:04:32] <fenn> wow $80 is getting up there
[03:05:00] <tomp2> still near a buck a point
[03:05:11] <skunkworks> SWPadnos thinks for 80 - you should just buy a another mesa :)
[03:05:15] <fenn> i bet you could etch your own, looks simple enough
[03:05:28] <fenn> if one were so inclined
[03:09:18] <fenn> there's got to be a PCI interface layout on the net somewhere
[03:11:53] <tomp2> there were isa 8255 diy projects, never found a pci one, then found futurlec & stopped lookin
[03:12:22] <tomp2> the futurlec uses a specialized pci interface chip, the 'tiger'
[03:14:00] <tomp2> and there's 8255's hung pff the parallel port too
[03:14:14] <tomp2> http://shop.cpu.com.tw/product_info.php/cPath/38_180_508/products_id/5108
[03:14:35] <fenn> that's not quite as cool
[03:15:11] <fenn> definitely more diy-able though
[03:15:59] <fenn> i'm trying to figure out what the open graphics project used
[03:18:48] <fenn> i guess it's part of the fpga
[03:19:27] <tomp2> whats teh 'XP10 PCI Bridge' on the schematic?
[03:19:35] <tomp2> top left 2nd page
[03:20:05] <tomp2> yeh htatsits between pci buys and the fpga's
[03:20:23] <tomp2> yeah that sits between the pci bus and the fpga's
[03:21:11] <fenn> 1x Secondary FPGA
[03:21:12] <fenn> Lattice XP10 (datasheet, mirror)
[03:21:13] <fenn> The Lattice XP10 non - volatile, reprogrammable FPGA (LFXP10e-5fn256c)is used for PCI communication.
[03:22:11] <tomp2> http://fr.xgitech.com/products/products_2.asp?P=15&CTID=%7B13D0E60D-0EAE-495F-8682-F4E3A8F78734%7D
[03:22:36] <tomp2> Volari™ XP10 feature PCI Express X1/X8/X16 interface
[03:23:35] <tomp2> so this opengraphics is an open design video card, cool
[03:24:08] <fenn> what is this volari xp10? it looks like a GPU
[03:24:41] <tomp2> the co build lotsa grfx chips, i thought it might be the XP10 used on this opesgraphics card
[03:25:05] <tomp2> its a pci interface
[03:26:02] <tomp2> your right, its a grfx engine too
[03:28:47] <tomp2> heh, drill down on the XP10 to find 'linux driver' , takes you to a page 'linux unified driver' thats sez 'no data' :-)
[03:29:45] <tomp2> but goodies here http://fr.xgitech.com/sd/sd_opensource.asp linux drivers for some chips sets
[03:30:29] <fenn> meh
[03:31:02] <Guest706> does ppmc can do io&servo on a same epp ?
[03:32:46] <cradek> yes
[03:33:01] <cradek> I know you can stack several cards on one port (I don't know how many)
[03:33:23] <cradek> I think the card cage has 6 or so slots
[03:34:15] <Guest706> how can it address those?
[03:34:38] <tomp2> if you need 8255 and 8253, JDR has 2 models, isa and pci ( 8253 for programmable timer counter , 8255 for io )
[03:34:51] <tomp2> bbl
[03:35:01] <cradek> I'm no expert, sorry, but I've worked on machines using ppmc
[03:36:01] <cradek> these had 3-4 of the cards all on one parport
[03:37:17] <Guest900> i disconnected
[03:37:41] <cradek> http://www.mpm1.com:8080/machines/GandL/pictures/S1030216.JPG
[03:37:45] <Guest900> anybody know how exactly ppmc address it's cards
[03:37:50] <cradek> the upper metal box is the ppmc cardset
[03:38:01] <cradek> looks like you can have 8 cards, this machine used 7
[04:39:35] <Guest176> how ppmc address slot/cards?
[04:43:02] <Guest176> what is the irc archeve address?
[04:46:47] <fenn> logger_emc: bookmark
[04:46:47] <fenn> Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2008-03-29.txt
[04:47:22] <SkinnYPupp> http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/
[05:04:54] <Guest176> does anybody know how ppmc is addressed
[05:17:47] <Guest176> ?
[05:18:20] <fenn> i dont understand the question
[05:18:33] <fenn> do you know how to use halcmd?
[05:19:38] <fenn> it should show up as ppmc.0... if you load the sample config
[10:02:27] <alex_joni> good morning all
[10:03:49] <Vq^> good morning mr Joni
[10:06:29] <alex_joni> what's up captain?
[10:07:24] <Vq^> mostly coding
[10:07:32] <alex_joni> on what?
[10:07:51] <Vq^> oh, i have a couple of projects running
[10:08:26] <Vq^> a l-system generator for a school project and an emc frontend for my company
[10:11:02] <Vq^> i've also just completed another school assignment, a very fast sudoku solver :) http://arda.no-ip.org/Sudoku.hs
[10:11:31] <Vq^> whats up on your end?
[10:11:39] <Vq^> any fun machine projects?
[10:13:48] <alex_joni> hmm.. not really machine projects
[10:14:14] <alex_joni> is that haskell?
[10:14:42] <Vq^> yeah
[10:17:25] <alex_joni> nice
[10:56:04] <BigJohnT> alex_joni: you there?
[11:03:56] <alex_joni> yup
[11:06:10] <BigJohnT> I cut a sheet of 12 gauge up into little bits yesterday with the cnc plasma cutter
[11:06:36] <BigJohnT> YEA!
[11:07:18] <BigJohnT> thanks for all your help
[11:09:50] <alex_joni> nice :)
[11:09:56] <alex_joni> we need proof obviously
[11:10:08] <alex_joni> some pictures and a couple movies from the action
[11:11:01] <BigJohnT> I was too busy running it to take a movie but I was thinking about it
[11:12:03] <BigJohnT> From yesterdays run I see I need to make a remote pendant for sure.
[11:12:20] <BigJohnT> The CNC EMC part worked perfectly
[11:12:22] <alex_joni> cool
[11:12:33] <alex_joni> happy to hear that
[11:12:54] <BigJohnT> can you start the g code from a pendant?
[11:13:00] <alex_joni> sure
[11:13:15] <alex_joni> we have a component called halui
[11:13:28] <alex_joni> which basicly enables you to do most things you could do from a regular GUI
[11:13:32] <alex_joni> but using hal pins
[11:13:34] <BigJohnT> hmmm I have not looked at it yet
[11:13:41] <alex_joni> man halui
[11:13:46] <BigJohnT> ok that is what I need
[11:14:08] <BigJohnT> my linux machine is up in the shop so I can't look
[11:15:44] <alex_joni> http://www.linuxcnc.org/docview/2.2/html//gui_halui.html
[11:18:17] <BigJohnT> Thanks
[11:20:29] <BigJohnT> Looks like it has everything I need, cool
[11:22:41] <alex_joni> BigJohnT: cool
[11:24:17] <BigJohnT1879> finally got my irc setup on this box
[11:25:57] <alex_joni> nice
[11:27:19] <BigJohnT> is a u32 an unsigned number?
[11:28:59] <alex_joni> yup
[11:29:04] <alex_joni> s32 is a signed number
[11:29:55] <BigJohnT> ok, kinda thought so but it is real early for me on my first cup of coffee
[11:32:48] <alex_joni> hmm.. wouldn't know how that is
[11:34:17] <BigJohnT> coffee or real early?
[11:34:24] <alex_joni> coffee :)
[11:35:11] <BigJohnT> u drink tea for breakfast?
[11:36:42] <alex_joni> BigJohnT: I guess, or various jiuces
[11:38:31] <BigJohnT> so to make a pick and place that runs over and over the same g code you could use halui to trigger the code based on an external input?
[11:38:46] <alex_joni> you could
[11:39:03] <alex_joni> or you can make an o-word loop
[11:39:09] <alex_joni> with M66 waiting for the input :)
[11:39:43] <BigJohnT> ok, that makes sense
[11:39:58] <BigJohnT> just thinking out loud a bit
[11:40:14] <alex_joni> thinking is good
[11:49:41] <alex_joni> whee .. big fishee http://www.practicalfishkeeping.co.uk/pfk/pages/item.php?news=661
[11:52:50] <BigJohnT> don't think I want to noodle that one...
[11:54:10] <BigJohnT> http://www.youtube.com/watch?v=biL-QcviQGk
[11:57:15] <alex_joni> ouch
[13:48:37] <BigJohnT> hi micges:
[13:49:33] <micges> hi BigJohnT
[13:50:07] <BigJohnT> I cut metal with my plasma cutter yesterday for the first time
[13:50:31] <micges> great
[13:50:46] <micges> how its going
[13:50:49] <BigJohnT> yea, been waiting for this moment
[13:50:58] <BigJohnT> everything works well
[13:51:18] <BigJohnT> I used the drag tip instead of THC
[13:51:41] <micges> what is drag tip ?
[13:52:00] <BigJohnT> it keeps the plasma cutter a fixed distance from the work
[13:52:04] <micges> THC is qiute complicated
[13:52:07] <BigJohnT> normally for hand cutting
[13:52:23] <micges> I see
[13:52:25] <BigJohnT> I have a floating mount so the drag tip worked great
[13:53:54] <micges> your drag tip uses analog->digital conversing that you asked some time ago ?
[13:55:03] <micges> as I remember you want to emc drive your Z axis
[14:05:51] <BigJohnT> yes, that is next
[14:06:17] <BigJohnT> actually I need to build a remote pendant next
[14:14:14] <awallin> hi all
[14:14:56] <awallin> hm, my ubunutu just booted once and mounted the whole file-system as read only
[14:15:19] <awallin> now it doesn't want to boot and says 'disk error' just after selecting OS un grub ??
[14:15:33] <awallin> better run to the store and get a SATA disk before it closes in 2h ??
[14:18:16] <awallin> * awallin is buying a new disk...
[14:20:02] <BigJohnT> bbl
[14:36:34] <tomp> is mounting readonly normal sometimes? maybe for the times when the disk check is needed ( "mounted N times, disk check forced" ) or, before it is re-mounted r/w ?
[14:36:55] <alex_joni> in the early stage I think it mounts ro
[14:37:04] <tomp> yeh, thought so
[15:05:54] <JymmmEMC> could always install SMART tools as well
[15:23:50] <JymmmEMC> SWPadnos: ?
[15:26:04] <JymmmEMC> SWPadnos: Note: The safety inputs of these products are described as normally closed (N.C.), ie. with the guard closed, actuator in place (where relevant) and the machine able to be started.
[15:31:46] <tom1> an old idea: the 'security link', its a series of NC contacts , any one of which drops out the basic control voltage ( on old machines, a 24V ac supply ] X
[15:32:12] <JymmmEMC> tom1 ?
[15:32:30] <tom1> door switches, hard limits, over/under voltage, fire sensor, etc
[15:32:52] <JymmmEMC> tom1: This is in respect to a specific safety relay.
[15:33:25] <JymmmEMC> It's manuals are not as clear as they should be
[15:42:46] <JymmmEMC> alex_joni: ping
[15:43:25] <alex_joni> JymmmEMC: pong
[15:43:42] <JymmmEMC> alex_joni: You play w/ safety relays alot?
[15:44:06] <alex_joni> hmm, alot might be exagerated
[15:44:28] <alex_joni> I have to debug safety circuits once in a while..
[15:45:34] <JymmmEMC> alex_joni: Take a look at the data sheet and installation instructions and tell me if you can make anything out of it, they're not as clear as they should be http://www.sti.com/relays/SR203M-A/index.htm
[15:45:50] <JymmmEMC> alex_joni: SR203AM01 is the ones I have
[15:46:35] <alex_joni> crap, need to register
[15:46:35] <JymmmEMC> alex_joni: They manuals for their other safety relays come with circuit exmaple sheets, just not this particular model... DOH!
[15:46:42] <JymmmEMC> alex_joni: no you dont
[15:46:53] <JymmmEMC> alex_joni: oh, use "nobody" as the userid
[15:46:59] <JymmmEMC> =)
[15:48:23] <alex_joni> * alex_joni reads the installation instructions
[15:48:52] <alex_joni> seems similar to the ones I use
[15:48:52] <JymmmEMC> alex_joni: Note, this will be configured for MANUAL reset, not AUTO.
[15:49:26] <JymmmEMC> alex_joni: Sure, seems simular to the SR16 too, but a whole lot different too =)
[15:50:06] <alex_joni> I guess you are familiar with the general way this works?
[15:50:21] <alex_joni> at least the ones I have (have quite the same logic I think):
[15:50:27] <alex_joni> you power A1/A2
[15:50:40] <JymmmEMC> alex_joni: Of the SR16AM yes. The SR203AM is a differetn animal
[15:50:44] <alex_joni> and the same power is fed through all of the estop chain into S12 and S52
[15:51:13] <JymmmEMC> alex_joni: This out has outputs and inputs both NO and NC
[15:51:23] <alex_joni> NO inputs? where?
[15:51:35] <JymmmEMC> heh, keep reading =)
[15:51:56] <awallin> what is the Ubuntu version recommended for EMC2 right now? still 6.06LTS ?
[15:52:17] <alex_joni> JymmmEMC: I'm only looking at the wiring examples at the moment
[15:52:23] <alex_joni> awallin: at the moment, yeah
[15:52:41] <DanielFalck> awallin: you can run the simulator in the newest version
[15:53:03] <DanielFalck> 7.10 is what I'm using
[15:53:09] <awallin> ok, so I'll just boot the new machine off the 6.06 cd then...
[15:53:11] <JymmmEMC> alex_joni: This is the SR16AM, and I completely understand this one, but it's manual has more concise information... http://www.sti.com/ltr2/access.php?file=pdf/4796.pdf
[15:54:34] <alex_joni> JymmmEMC: look at SR203 Circuit Diagramm
[15:54:54] <alex_joni> page 2 of the installing instructions (STI_IS_SR203M_57516_4.gxd.pdf here)
[15:54:55] <JymmmEMC> k
[15:55:17] <alex_joni> A1 and A2 are clear I presume
[15:55:59] <JymmmEMC> alex_joni: I can accoutn and understand 12 points except for: S11,s12,s52,s22
[15:56:20] <alex_joni> ok, lets leave S11 and S21 out for now
[15:56:37] <alex_joni> S12 and S52 are the two security channels
[15:56:45] <alex_joni> S12 is channel 1 (K1)
[15:56:51] <alex_joni> and S52 is channel 2
[15:57:01] <alex_joni> basicly it works like this..
[15:57:36] <alex_joni> when A1 & A2 is powered, S11 gives you the output power connection (e.g. 24V as on A1)
[15:57:40] <JymmmEMC> alex_joni: look at "Connectons" below the doagram
[15:57:50] <alex_joni> disregard that, it seems bogus
[15:58:23] <alex_joni> the idea is that you feed 24V through a series of NC contacts (your estop mushrooms and whatnot) and at the end you feed them into S12 and S52
[15:58:45] <alex_joni> there are 2 channels, because (at least in europe) you need to have everything redundant
[15:59:02] <alex_joni> each mushroom must have 2 contacts (one for channel 1, one for ch 2)
[16:00:10] <JymmmEMC> alex_joni: I really do understand the principals of a safety relay, I wired up the SR16 no problem. It's *THIS* specific relay (which has 8 additional connections) that's a bit puzziling in it's operation (eg what is what in which condition)
[16:01:22] <alex_joni> I think they really mean to express something else in the "connections" paragraph
[16:01:34] <alex_joni> S11 & S52 = safety input NC
[16:01:51] <alex_joni> that really means that if there's a wire between S11 and S52, then everything is ok
[16:02:00] <alex_joni> (which is exactly what I said before..)
[16:02:05] <JymmmEMC> alex_joni: Yeah, well I come to realize that in a safety relay if you think backwards, it backs sense
[16:02:30] <JymmmEMC> as it's designed to STOP things, not start them (for safety purposes that is)
[16:02:31] <alex_joni> JymmmEMC: I would wire it as I told you..
[16:02:55] <alex_joni> from S11 to your estop circuitry (all NC's) then to S12 and S52
[16:03:08] <alex_joni> when something opens it will open K1 and/or K2
[16:03:18] <JymmmEMC> alex_joni: This relay has a output that will say (as example) "Help ME" illuminates a lamp to let you know that ESTOP has been activated.
[16:03:42] <alex_joni> then after the ext. condition is gone, it won't get reset until you connect S34 with S11 I think
[16:04:07] <JymmmEMC> alex_joni: Reset is S12/S34 actually
[16:04:24] <alex_joni> can't be S12
[16:04:33] <alex_joni> well.. actually it's the same
[16:04:39] <JymmmEMC> alex_joni: It is, look at he "connections" chart
[16:04:47] <alex_joni> if you do S12/S34, then you can only reset if the external circuit is ok
[16:05:00] <alex_joni> but S12 is connected to S11 (through your estop circuit..)
[16:05:01] <JymmmEMC> alex_joni: EXACTLY=)
[16:05:19] <JymmmEMC> No, you only want to reset when all conditions have been cleared
[16:05:23] <alex_joni> either way, if S12 or S52 have no power, you can reset all you want
[16:05:26] <alex_joni> nothing will happen
[16:05:49] <JymmmEMC> alex_joni: Look at the other PDF on that url I gave
[16:05:59] <alex_joni> if anything happens, then you should just toss out the SR203 ;)
[16:06:12] <JymmmEMC> lol
[16:06:43] <JymmmEMC> alex_joni: pg2 of the other PDF
[16:06:55] <JymmmEMC> "data sheet"
[16:07:21] <alex_joni> yeah, I saw that
[16:07:31] <alex_joni> (like the SR203 better)
[16:07:37] <JymmmEMC> alex_joni: Bottom of pg2 "Terminal Connections"
[16:07:56] <JymmmEMC> alex_joni: they are both the same device, different PDF's
[16:08:38] <alex_joni> hang on, you just told me to look at the pdf you sent me
[16:08:46] <alex_joni> that was the SR16AM
[16:09:00] <JymmmEMC> alex_joni: Sorry, we have a failure to communicate =)
[16:09:13] <JymmmEMC> http://www.sti.com/ltr2/access.php?file=pdf/2583.pdf
[16:09:31] <alex_joni> you never sent me that
[16:09:52] <JymmmEMC> alex_joni: The SR16 data sheet I was showing you that it has more information than the SR203
[16:10:02] <JymmmEMC> alex_joni: It was on the original url I gave you.
[16:10:15] <JymmmEMC> before you logged in
[16:10:17] <alex_joni> this is still SR16
[16:10:32] <JymmmEMC> stupid copy n paste
[16:10:59] <JymmmEMC> http://www.sti.com/ltr2/access.php?file=pdf/4089.pdf
[16:11:40] <alex_joni> ok, I have it open
[16:11:43] <alex_joni> page 2?
[16:12:17] <alex_joni> that's a typical US schematic :P (only one channel used)
[16:13:39] <alex_joni> I'm not sure I understand what "Reset" is supposed to do there..
[16:14:07] <alex_joni> ahh, sorry.. yeah, I understood now (didn't properly read the NC contacts from the external K1 and K2)
[16:14:23] <alex_joni> * alex_joni hates when people name different things the same..
[16:14:42] <JymmmEMC> lol
[16:14:54] <JymmmEMC> oh man.... http://www.mercurynews.com/ci_8739025?nclick_check=1
[16:15:25] <alex_joni> JymmmEMC: so what's not clear for you?
[16:16:02] <alex_joni> btw, that mercury link doesn't open here
[16:16:44] <JymmmEMC> http://www.google.com/search?lr=&ie=UTF-8&oe=UTF-8&q=Roadshow%3A%20%241%2C200%20a%20month%20fuels%20long%20commutes
[16:16:54] <JymmmEMC> first link
[16:17:37] <alex_joni> yeah, found it..
[16:17:48] <alex_joni> what can I say.. join the rest of the world with high gas prices
[16:18:08] <JymmmEMC> fucking bush
[16:19:52] <alex_joni> well.. everyone with his own sexual preferences
[16:20:38] <JymmmEMC> alex_joni: Ok, before I stripped out the cabinet this was in, it was setup pretty cool... The BRB would light up when ESTOP was engaged. Also, the RESET button would light up when it was READY to be reset. I'm just trying to duplicate those functions again.
[16:22:27] <alex_joni> ok, BRB light you can connect to 41/42
[16:22:40] <alex_joni> and I would connect the RESET light to S12
[16:25:00] <JymmmEMC> alex_joni: where did you get S12 from in this respect?
[16:25:11] <alex_joni> just before the reset button
[16:25:39] <JymmmEMC> I know WHERE it is, but I mean the logic in your decision
[16:25:47] <alex_joni> I don't understand
[16:26:05] <awallin> is it possible that a relatively modern BIOS can't boot an OS that's installed at the end of a 250GB disc?
[16:26:09] <JymmmEMC> S12/S34 is RESET (input)
[16:26:21] <JymmmEMC> awallin: which OS ?
[16:26:32] <awallin> freshly installed ubuntu 6.06
[16:26:35] <alex_joni> JymmmEMC: no, S34 is RESET input
[16:26:54] <alex_joni> S12 is the input to channel 1
[16:26:58] <JymmmEMC> awallin: what happens when you try? Just get a blinking cursor?
[16:27:19] <awallin> JymmmEMC: yep, I get the bios screen and then a blinking cursor
[16:27:30] <JymmmEMC> awallin: you're missing the MBR
[16:27:30] <alex_joni> and in the diagram at page 2 (4089.pdf) the S12 is used to allow for pushing reset
[16:27:52] <alex_joni> boot the rescue disk, install grub
[16:27:58] <awallin> JymmmEMC: I did the partitions with the ubuntu installer, sholdn't it do that for me?
[16:28:10] <JymmmEMC> awallin: If it should, it didn't.
[16:28:20] <JymmmEMC> awallin: do as alex_jonisuggested
[16:28:40] <JymmmEMC> awallin: do as alex_joni suggested
[16:28:51] <awallin> hm, is grub on the install cd?
[16:29:01] <alex_joni> awallin: sure
[16:29:40] <awallin> ok, I'll try
[16:32:13] <JymmmEMC> you have to update grub more than likely, but if you're missing the MBR, you just might not have a partition marked as bootable
[16:32:43] <JymmmEMC> * JymmmEMC cheats and just copies the MBR to a file anymore =)
[16:34:55] <awallin> hmh, how would I install grub from the install cd? apt-get install grub says grub is already the newest version
[16:35:10] <JymmmEMC> Backup MBR: dd in=/dev/sda of=/dev/sdb1/sda.mbr count=1 bs=512
[16:35:28] <JymmmEMC> Backup MBR: dd if=/dev/sda of=/dev/sdb1/sda.mbr count=1 bs=512
[16:36:01] <JymmmEMC> Restore MBR: dd if=/dev/sdb1/sda.mbr of=/dev/sda
[16:36:03] <JymmmEMC> =)
[16:36:08] <JymmmEMC> run grub?
[16:37:17] <JymmmEMC> (not the backup/restore of MBR does NOT work with extended partitions)
[16:37:24] <JymmmEMC> (note: the backup/restore of MBR does NOT work with extended partitions)
[16:37:33] <JymmmEMC> that's a different procedure
[16:40:15] <awallin> setting the bootable flag for the partition with fdisk did not work
[16:43:07] <alex_joni> awallin: you need to set it active, then run grub
[16:45:26] <alex_joni> awallin: try grub-install
[16:53:16] <awallin_ubuntu> hello from ubuntu...
[16:53:34] <tomp> success?
[16:53:53] <awallin_ubuntu> yeah, just labeled the newly installed partition as bootable
[16:54:01] <awallin_ubuntu> the cd didn't do that for some reason...
[16:54:22] <tomp> great ( but check others )
[16:55:07] <awallin_ubuntu> 278M of updates suggested by the package manager...
[16:55:25] <tomp> just look by running fdisk, no need to change what works
[16:56:31] <awallin_ubuntu> hm, ubuntu doesn't suggest the native resolution of my screen, where would I add that?
[16:57:04] <alex_joni> awallin_ubuntu: /etc/X11/xorg.conf :)
[16:57:49] <tomp> native revolution
[16:57:56] <alex_joni> heh :)
[16:58:30] <tomp> is a 12-24 tap rare? (how many stores must i visit?)
[16:58:45] <DanielFalck> tomp: not rare, I have some
[16:58:55] <tomp> could you email me one?
[16:59:00] <DanielFalck> got them from MSC, I think
[16:59:15] <DanielFalck> sure, check your mail right now : )
[16:59:22] <tomp> ok, will check J&L in chicago ( i think msc owns them now )
[16:59:41] <DanielFalck> yes, J & L is good- we use them all the time
[17:05:57] <alex_joni> http://www.earth-policy.org/Books/PB3/Contents.htm
[17:07:39] <awallin_ubuntu> has anyone here made worm-gears with a lathe?
[17:08:02] <DanielFalck> we have at work on a CNC lathe
[17:08:12] <DanielFalck> the worms anyway
[17:08:52] <awallin_ubuntu> ok, a lathe retrofit would be a nice project after I get this mill goign...
[17:09:19] <tomp> alex_joni: my current bedside book http://www.randomhouse.com/crown/livinglikeed/index.html
[17:09:36] <tomp> simple tricks to get greener
[17:18:59] <tomp> 'making a worm gear' http://bbs.homeshopmachinist.net/showthread.php?t=20096
[17:20:06] <tomp> http://www.atmsite.org/contrib/JSAPP/wormgear/wormgear.html some nice info out there
[17:22:06] <awallin_ubuntu> tomp: thanks. telescope drive was my intended use :)
[17:22:39] <tomp> there'
[17:22:51] <tomp> 's even a video, but its pay for
[17:23:17] <tomp> 4 hours of gear hobbing, sounds like a fun evening
[17:24:13] <tomp> the heck with this 12-24 tap, a 5mm x 0.5 will do as well
[17:29:58] <awallin_ubuntu> system restart required.
[17:42:18] <awallin> how do I set the resolution in ubuntu. The GUI doesn't give me 1280x1024 as an option. Adding "1280x1024" to the xorg.conf doesn't help.
[17:44:08] <alex_joni> awallin: I'm not sure what the proper ubuntu way is
[17:44:13] <alex_joni> but sometiems adding a modeline helps
[17:44:25] <alex_joni> check /var/log/Xorg.log or whatever the logname is
[17:44:32] <alex_joni> it usually tells you what modes it tries
[17:46:41] <cradek> awallin: probably it wasn't able to read your monitor's info at install time, so the monitor specs in xorg.conf are wrong.
[18:01:53] <awallin_ubuntu> was there a latency-test somewhere with 2.2.4 ?
[18:05:16] <cradek> awallin: yes it's called latency-test :-)
[18:06:57] <jack_live> hi peoples
[18:07:39] <jack_live> i use the mach to 3 years would be possible to leave the interfaçe AXIS with some of the functions of the first screen of mach?
[18:08:16] <awallin_ubuntu> cradek: thanks. nice. I'm getting around 34000 for max interval on the 25us base thread, jitter 10000.
[18:08:30] <alex_joni> we don't use mach, so it's a bit unclear what you need
[18:09:37] <cradek> jack_live: since emc2 is free/open source software, you are free to modify it however you want. however, if you have very specific feature requests that you think might interest the rest of the users, you can file a request on sourceforge.
[18:09:48] <jack_live> for example time of milling online
[18:09:56] <cradek> jack_live: file/properties
[18:10:11] <awallin_ubuntu> cradek, alex_joni: would a jitter of around 10000 for the 1ms thread and 17000 for the 25us thread be considered OK?
[18:10:41] <cradek> that seems fine to me
[18:11:38] <jack_live> good but is possible show it online?
[18:11:51] <cradek> I don't understand what you mean by online
[18:12:18] <jack_live> machine runing numbres in my eyes
[18:12:29] <cradek> brb
[18:25:38] <jack_live> good but is possible show it in realtime
[18:25:51] <jack_live> sorry my english is bad
[18:33:11] <alex_joni> jack_live: it's not quite clear what you mean
[18:33:15] <alex_joni> (at least not to me)
[18:39:43] <jack_live> Is the following as the use mach a long time that I had on the screen axis of some functions that are in mach eg time used in machining
[18:40:15] <jack_live> sorry my english not strong
[18:46:48] <alex_joni> you mean how much time is left to machine?
[18:46:56] <alex_joni> (to finish the program?)
[19:05:04] <jmkasunich> awallin: another page about worms for telescope drives: http://www.astronomiainumbria.org/advanced_internet_files/meccanica/easyweb.easynet.co.uk/_chrish/worms.htm
[19:15:13] <awallin> jmkasunich: thanks, looking.
[19:17:03] <jmkasunich> I've made worm gears before, but relatively low tooth count (28) and I used a mill, not a lathe
[19:17:24] <jmkasunich> gashed with dividing head, the free-hobbed
[19:17:29] <jmkasunich> then
[19:50:45] <skunkworks> jmkasunich: nice link. I sent it to a coworker I am trying to get into machining :). Big telescope person that likes making mods for his scopes.
[19:51:51] <skunkworks> btw - our machine shop is finally getting a cnc. with a 'gasp' centroid control.
[19:51:55] <skunkworks> bed mill.
[19:52:58] <skunkworks> The head guy is old school machinist.. Doesn't like cnc. We have tried to get him to buy a older mill to fix up.. They could get 3 for the price they are paying for this mill
[19:53:56] <skunkworks> It will have conversational programming - so that will be neat to see. I have not been exposed to it before.
[20:31:19] <tomp> http://www.centroidcnc.com/conversational.htm
[22:10:05] <alex_joni> good night all
[22:14:49] <BigJohnT> good night alex
[22:32:09] <BigJohnT> up late micges?
[22:34:10] <micges> yes, must check plan for tommorow stuides
[22:34:32] <micges> here is just 11:30 pm :)
[22:34:35] <BigJohnT> cool
[22:35:15] <BigJohnT> 5:30 pm here
[22:36:23] <micges> did you run any more cutting today ?
[22:37:01] <BigJohnT> no, we bent the parts up and welded them together today.
[22:37:29] <BigJohnT> I did plan some improvements today in material handling
[22:38:17] <BigJohnT> now I'm cleaning up the mess down here in the beer cave
[22:38:17] <micges> how is it handled now ?
[22:38:26] <BigJohnT> not very well LOL
[22:38:37] <BigJohnT> we put it up on saw horses
[22:39:11] <BigJohnT> because it is portable I had to devise a portable support system for the sheet of steel
[22:40:19] <micges> I see
[22:40:54] <BigJohnT> most of the time I will cut 3mm plate some times maybe 6.4mm
[22:41:04] <micges> on ours mills sheet are handled by vacuum table
[22:41:32] <BigJohnT> do you pressure the table to move the sheet?
[22:41:59] <BigJohnT> like an air hockey table...
[22:43:29] <micges> no
[22:44:04] <micges> air is pumped from under the sheet
[22:45:50] <BigJohnT> to hold it in place?
[22:46:18] <micges> yes
[22:47:54] <micges> hold on I show you how that table look like, looking for pics
[22:49:16] <BigJohnT> ok
[22:56:54] <micges> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Micges
[22:56:58] <micges> last pics
[22:57:50] <micges> under table is 15 mm free space
[22:58:05] <micges> and pump is about 1,5 KW
[22:58:10] <micges> works great
[23:00:20] <BigJohnT> cool
[23:01:03] <BigJohnT> is that you in the picture
[23:01:31] <micges> no, my stupid boss :P
[23:07:05] <BigJohnT> what do your machines make?
[23:08:18] <micges> this one is for "pertinax"
[23:08:52] <BigJohnT> hmmm, what is that?
[23:10:20] <micges> form in thin very hard material to make rows in paper
[23:10:57] <BigJohnT> ok
[23:11:46] <micges> to make boxes easy to fold up
[23:14:33] <BigJohnT> cool
[23:15:58] <micges> and this is me: http://imagebin.org/15393
[23:16:07] <micges> really :)
[23:17:04] <BigJohnT> with dreadlocks!
[23:17:20] <micges> yup
[23:17:30] <BigJohnT> cool
[23:18:14] <BigJohnT> and this is me: http://i47.photobucket.com/albums/f163/johnplctech/hunting/HPIM0281.jpg
[23:19:19] <micges> with small gun :D
[23:19:30] <SkinnYPupp> Ha ..
[23:19:30] <BigJohnT> 50 caliber
[23:19:37] <BigJohnT> 1/2" bore
[23:19:56] <BigJohnT> electronic ignition
[23:20:13] <micges> nice
[23:20:30] <micges> you live near forests ?
[23:21:14] <BigJohnT> I live in the forest
[23:21:33] <micges> cool
[23:21:35] <BigJohnT> hardwood forest of the ozark foothills
[23:21:51] <BigJohnT> I can pee off my deck and no one can see me LOL
[23:22:17] <micges> hehe
[23:22:45] <micges> how far is to nearby town ?
[23:22:58] <BigJohnT> 20 miles
[23:23:00] <BigJohnT> not bad
[23:23:15] <toastydeath> must be nice =(
[23:23:16] <BigJohnT> 3 hours from any big cities
[23:23:22] <BigJohnT> very nice
[23:24:21] <micges> and neibours ?
[23:24:32] <BigJohnT> I built my own house about 10 years ago with my wifes help
[23:25:08] <BigJohnT> there are 6 houses on about 50 acres on my road
[23:26:03] <BigJohnT> I live in the middle of 9 acres
[23:26:59] <micges> and what is name of village ?
[23:28:08] <micges> In Poland is hard to find that kind of place
[23:28:12] <BigJohnT> Poplar Bluff, do a google map on 63901 the zip code here and look at the satilite photo
[23:30:53] <BigJohnT> too many people too little land?
[23:31:13] <micges> some sort of that
[23:32:34] <micges> I live in Torun, central Poland
[23:35:22] <BigJohnT> some pictures of the night lights of Torun look nice
[23:35:56] <LawrenceG> BigJohnT: http://imagebin.ca/view/vosbXx.html
[23:36:05] <micges> yes its very nice
[23:36:19] <LawrenceG> a long drive to your house!
[23:37:43] <BigJohnT> from BC yes it is
[23:38:26] <BigJohnT> you should make the trip from New Orleans to Anchorage when the AlCan highway was 1200 miles of gravel and pot holes....
[23:38:32] <BigJohnT> now that is a trip or two
[23:39:09] <LawrenceG> 1 day 14 hours is what google says.... I think they mistake my pickup for a learjet!
[23:39:41] <LawrenceG> 4000km (2500 miles)
[23:40:31] <BigJohnT> It took 2 weeks to drive from New Orleans to Anchorage in the 60's
[23:42:50] <micges> must go sleep
[23:42:56] <BigJohnT> good night
[23:42:56] <micges> goodnight all

[23:52:21] <BigJohnT> my house is east of the one in the picture but it was not there in 1996 when the picture was taken
[23:57:52] <Ito-Brazil> Hello there
[23:59:14] <Ito-Brazil> Can I modify the AXIS interface?
[23:59:28] <Ito-Brazil> I mean I want to put more ainformation there like:
[23:59:51] <Ito-Brazil> Milling time and run from Line #
